[0029] In the description of the embodiments, "several", "plurality" and "multiple" represent at least 2. It can be any number such as two, three, four, five, six, seven, eight, nine, or even more than nine.

[0030] It should be noted that the license plate mentioned in the embodiment may be a finished product or a semi-finished product that has been processed into a plate.

[0031] Example 1

[0032] The utility model provides a license plate grabbing device, such as Figures 1 to 4 As shown, it includes a moving mechanism 1 and a grabbing mechanism 2, wherein the grabbing mechanism 2 has a connecting seat 21, and the connecting seat 21 is provided with a license plate grabbing unit and a paper grabbing unit, wherein the license plate grabbing unit can take and place the license plate, and the paper grabbing unit can take and place the paper; the moving end of the moving mechanism 1 is connected to the connecting seat 21, and the entire grabbing mechanism 2 is driven to move along a moving path by the moving end of the moving mechanism 1, and in the moving path of the grabbing mechanism 2, the license plate grabbing unit and the paper grabbing unit can pass above the same point respectively, and this point is defined as a storage point.

[0033] A point in the moving path of the grabbing mechanism 2 is defined as a grabbing point. When the grabbing mechanism 2 is at the grabbing point, the position where the license plate grabbing unit can grab the license plate is defined as a license plate grabbing station, and the position where the paper grabbing unit can grab the paper is defined as a paper grabbing station. When arranging the license plate production system, such as Figure 5 As shown, the discharging end of the license plate conveying device 3 is arranged at the license plate grabbing station, and the feeding end of the paper feeding device 4 is arranged at the paper grabbing station.

[0034] When the license plate begins to be stored, the box for storing the license plate is placed at the storage point. When the previous processing step transports the license plate to the license plate grabbing station through the license plate conveying device 3, the mobile mechanism 1 moves the grabbing mechanism 2 to the grabbing point. At this time, the license plate at the license plate grabbing station is grabbed by the license plate grabbing unit, and at the same time, the paper at the paper grabbing station is grabbed by the paper grabbing unit; after the license plate grabbing unit and the paper grabbing unit complete the grabbing operation, the mobile mechanism 1 drives the grabbing mechanism 2 to continue to move; in the process of the grabbing mechanism 2 moving along the moving path, the license plate grabbing unit and the paper grabbing unit pass through the storage point respectively, and alternately put the grabbed license plate and paper into the box, and repeat this process so that the license plate and paper are stacked in the box one by one.

[0035] Therefore, through the cooperation of the moving mechanism 1 and the grabbing mechanism 2, the license plate and the paper can be grabbed automatically at the same time, and the license plate and the paper can be placed one by one, so that the license plates can be stacked and stored while the paper is placed between adjacent license plates, ensuring the quality of the finished product when the license plates are stored. The whole process does not require human participation, reducing the cost of long-term operations and improving efficiency.

[0036] It can be understood that the present device can use a single mobile mechanism 1 to transport the license plate and the paper at the same time. Compared with the method of setting up two mobile mechanisms 1 to move the license plate and the paper respectively, the present device reduces the number of mobile mechanisms 1 and saves costs. At the same time, compared with the method of moving the license plate and the paper respectively by performing two movements of one mobile mechanism 1, the present device reduces the number of movements of the mobile mechanism 1 and improves efficiency.

[0037] The moving mechanism 1 can be a driving device that can drive the grabbing mechanism 2 to move along a simple path, such as a cylinder that can drive the grabbing mechanism 2 to move along a straight path. At this time, the license plate grabbing unit and the paper grabbing unit can both be located on the straight path, and the storage point can be located directly below the straight path. Thus, when the grabbing mechanism moves, the license plate grabbing unit and the paper grabbing unit can both move along the straight path and pass through the storage points respectively, to achieve alternating delivery of license plates and paper.

[0038] The moving mechanism 1 may also be a driving device that can move along a complex path, such as a mechanical arm. The mechanical arm drives the grabbing mechanism 2 to move along a preset moving path, wherein the preset moving path can be adaptively adjusted according to the relative positions between the license plate grabbing device, the license plate conveying device 3, the paper feeding device 4 and the storage point when the license plate production system is arranged, so that the license plate grabbing unit and the paper grabbing unit can cooperate with the license plate conveying device 3 and the paper feeding device 4 under the drive of the mechanical arm, so that the license plate grabbing unit grabs the license plate, and the paper grabbing unit grabs the paper at the same time; then, the grabbing license plate and the paper can be placed at the storage point in a fixed order, thereby circulating, and then realizing the alternating placement of multiple license plates and multiple papers. Due to the high degree of freedom of the mechanical arm, there are not too many requirements for the placement of the license plate grabbing device, the license plate conveying device 3, the paper feeding device 4 and the storage point, thereby reducing the accuracy requirements for the placement of each device when the license plate production system is arranged, and facilitating the arrangement of the license plate production system.

[0039] Among them, Figure 1 As shown, the moving mechanism 1 can be made into a six-axis robot arm to ensure that the moving mechanism has a high degree of freedom.

[0040] Among them, Figure 5 As shown, in the partial moving path to the grabbing point, it is preferred to approach the grabbing point from top to bottom, thereby facilitating the grabbing mechanism 2 to grab the plate surface of the license plate and avoiding the situation in which the license plate or paper is knocked away due to the lateral movement of the grabbing mechanism 2 during the movement.

[0041] The solution for the license plate grabbing unit to grab the license plate may be clamping, magnetic suction or negative pressure adsorption.

[0042] Based on the solution that the license plate grabbing unit grabs the license plate by negative pressure adsorption, in one or more embodiments, Figures 1 to 4 As shown, the license plate grabbing unit includes a plurality of suction pipes 22 connected to the negative pressure device, and the suction pipes 22 of the license plate grabbing unit are defined as license plate suction pipes 221. The plurality of license plate suction pipes 221 are connected to the connecting seat 21, and the suction ends of the plurality of license plate suction pipes 221 can contact the plate surface of the license plate at the same time. Thus, the license plate grabbing unit can grab the license plate by negative pressure adsorption, and through the cooperation of the plurality of license plate suction pipes 221, the plate surface of the license plate at the license plate grabbing station can be adsorbed at multiple points, thereby improving the grabbing strength and stability of the license plate by the license plate grabbing unit, and reducing the possibility of the license plate being offset or falling off during the grabbing process.

[0043] When the license plate grabbing unit passes above the storage point, the license plate suction tube 221 stops adsorbing the license plate, and the license plate can be dropped to the storage point.

[0044] The paper grabbing unit grabs the paper in a manner of clamping or negative pressure adsorption.

[0045] Based on the solution that the paper grabbing unit grabs the paper by negative pressure adsorption, in one or more embodiments, Figures 1 to 4 As shown, the paper grabbing unit includes a plurality of suction pipes 22 connected to the negative pressure device, and the suction pipes 22 of the paper grabbing unit are defined as paper suction pipes 222. The plurality of paper suction pipes 222 are connected to the connection seat 21, and the suction ends of the plurality of paper suction pipes 222 can contact the surface of the paper at the same time. Thus, the paper grabbing unit can grab the paper by negative pressure adsorption, and through the cooperation of the plurality of paper suction pipes 222, the surface of the paper in the paper grabbing station can be adsorbed at multiple points, thereby improving the gripping force and stability of the paper grabbing unit on the paper, and reducing the possibility of the paper being offset or falling off during the grabbing process.

[0046] When the paper grabbing unit passes above the storage point, the paper suction tube 222 stops sucking the paper, and the paper falls to the storage point.

[0047] Among them, Figure 3 As shown, the number of the license plate straws 221 is preferably four, which are used to absorb the four corners of the license plate respectively; the number of the paper straws 222 is preferably four, which are used to absorb the four corners of the paper respectively.

[0048] Based on this, in one or more embodiments, the connecting seat 21 can be a plate member, including two square plates and an intermediate connecting plate connecting the two square plates. At this time, the two square plates and one intermediate connecting plate form an "H"-shaped structure, and the moving end of the moving mechanism is connected to the intermediate connecting plate. The four corners of the surface of one square plate are used to respectively set four license plate straws 221, and the four corners of the surface of another square plate are used to respectively set four paper straws 222, thereby making it possible to divide the license plate straws 221 and the paper straws 222 for easy identification by operators.

[0049] The cooperation between each straw 22 (license plate straw 221 and paper straw 222) and the grasped object (license plate or paper) can be a rigid contact or a flexible basis.

[0050] Based on the flexible contact between the straw 22 and the grasped object, a flexible suction cup 23 may be provided at the suction end of each straw 22, thereby improving the adsorption capacity of the suction end of the straw 22 on the surface of the grasped object.

[0051] In one or more embodiments, the straw 22 and the connection seat 21 may be slidably connected, and the sliding direction of the straw 22 is parallel to the axis of the straw 22. When grabbing the grasped object, the axis of the straw 22 is made vertical, and the suction end of the straw 22 is located at the bottom of the straw 22, so that the entire grasping mechanism 2 approaches the grasped object from top to bottom until the suction end of the straw 22 abuts against the grasped object, thereby achieving suction and grasping of the grasped object. Through the sliding of the straw 22 relative to the connection seat 21, the straw 22 can adapt to the error of the grasping mechanism 2 when approaching the grasped object, ensuring that the suction end of the straw 22 can abut against the surface of the grasped object to achieve adsorption, and will not apply excessive squeezing force to the grasped object, thereby reducing the possibility of damage to the grasped object.

[0052] In one or more embodiments, Figure 2 and Figure 4 As shown, a sliding assembly can be provided between the straw 22 and the connection seat 21, and the straw 22 and the sliding assembly are slidably connected in a direction parallel to the axis of the straw 22; the sliding assembly and the connection seat 21 are slidably matched in a direction perpendicular to the axis of the straw 22, and the sliding assembly and the connection seat 21 are detachably connected, and after the sliding assembly is slid, the sliding assembly and the connection seat 21 can be relatively fixed, and at this time, the straw 22 and the connection seat 21 are slidably connected through the sliding assembly. By sliding the sliding assembly on the connection seat 21, the spacing between the straws 22 in the license plate grabbing unit or the paper grabbing unit can be adjusted, so that the license plate grabbing unit and / or the paper grabbing unit can adapt to objects of different specifications.

[0053] For the sliding component, specifically, Figure 4As shown, the sliding assembly may include a sleeve 24 and a plurality of nuts 25, wherein the sleeve 24 has an external thread, and the plurality of nuts 25 are threadedly connected to the outer side of the sleeve 24; wherein the sleeve 24 is sleeved outside the straw 22, and the straw 22 can slide in the sleeve 24 along the axis of the straw 22; the connecting seat 21 is provided with elongated holes 211 corresponding to the sliding assemblies one by one, and the sleeve 24 of each sliding assembly passes through the corresponding elongated hole 211, and can slide in the elongated hole 211 along the length direction of the elongated hole 211, wherein The length direction of the long hole 211 is perpendicular to the axial direction of the straw 22, thereby achieving sliding cooperation between the sliding component and the connecting seat 21 along the axial direction perpendicular to the straw 22; the outer diameter of the sleeve 24 is adapted to the width of the long hole 211, and the outer diameter of the nut 25 is larger than the width of the long hole 211. When the sleeve 24 slides to a suitable position in the long hole 211, the nut 25 can be rotated to clamp the portion of the connecting seat 21 around the long hole 211, thereby achieving a detachable connection between the sliding component and the connecting seat 21.

[0054] In order to prevent the straw 22 from directly falling off the sleeve 24 during the sliding process, two limiting protrusions 223 can be provided on the outer side of the straw 22. The two limiting protrusions 223 are spaced apart along the axial direction of the straw 22. At this time, the sleeve 24 is located between the two limiting protrusions 223. The sliding range of the straw 22 is limited by the two limiting protrusions 223 to prevent the straw 22 from falling off the sleeve 24. An elastic member 26 is provided between one or two limiting protrusions 223 and the sleeve 24. The suction end of the straw 22 always has a tendency to move away from the sleeve 24 under the action of the external force applied by the elastic member 26. Therefore, when grabbing the object, the suction end of the straw 22 can be closely abutted against the surface of the object, thereby ensuring that the straw 22 can adsorb the object.

[0055] The limiting protrusion 223 may be a nut threadedly connected to the straw 22 , so as to facilitate the disassembly and assembly of the straw 22 .

[0057] The utility model also provides a license plate production system, such as Figure 1 As shown, it includes a license plate conveying device 3, a paper feeding device 4 and any one of the license plate grabbing devices mentioned in Example 1, wherein the output end of the license plate conveying device 3 can output the license plate to the license plate grabbing station, and the feeding end of the IQ feeding device can output the paper to the paper grabbing station. When the grabbing mechanism 2 moves to the grabbing point, the license plate grabbing unit cooperates with the output end of the license plate conveying device 3, and the license plate grabbing unit can grab the license plate at the output end of the license plate conveying device 3; the paper grabbing unit cooperates with the feeding end of the paper feeding device 4, and the paper grabbing unit can grab the paper at the feeding end of the paper feeding device 4.

[0058] The license plate production system is used to produce and process license plates until finished products are produced and stored. Through the cooperation of the license plate conveying device 3, the paper feeding device 4 and the license plate grabbing device in the system, the degree of automation of license plate production and processing can be improved, manual participation can be reduced, and the production efficiency of the entire production system can be improved.
